ROOF-FLANGE.

Application led October 18, 1917. Serial No. 197,342.

To all 'whom t may concern:

Be it known that I, EDWARD F. DONNELLY, a citizen of the United States,residing at Malden, county of Middlesex, State of Massachusetts, haveinvented an Improvement in Roof-F langes, of which the followingdescription, in connection with the accompanying drawing, is aspecification, like characters on the drawing representing like parts.

This invention relates to roof flanges and has for its object to providea novel roof flange which is simple in its construction and inexpensiveto manufacture; which can be used equally well on a flat roof, a roofhaving a steep pitch, or a roof having any pitch between the two, andwhich has other advantages, all as will be more fully here- In order togive an understanding of my invention I have illustrated in the drawingsa selected embodiment thereof which will now be described, after whichthe novel features will be pointed out in the appended claim.

Figures 1, 2 and 3 are longitudinal vertical sections through a roofflange embodying my invention showing the flange applied to roofs ofdifferent pitch;

Fig. 4 is a top plan view of.a roof flange with a portion of theflashing broken out;

Fig. 5 is a section on the line 5 5, Fig, 4.

My improved roof flange is formed with a bottom 1 adapted to rest on theroof 2 and it `has a wall or curb 3 rising from the bottom 1 and forminga space to receive the usual packing 4. This wall or curb 3 has ageneral oval shape and the end portions 5 and 6 thereof are inclined inthe same direction relative to the plane of the bottom 1. The curb 3thus forms an oval space having its axis inclined to the bottom 1. Thewall or curb 3 is situated a slight distance from the peripheral edge 7of the bottom 1 so that a peripheral flange 8 is presented exterior tothe wall 3. 9 is the usual copper flashing which encircles the wall 3and rests on the flange 8, said flashing being preferably soldered tothe flange S, as shown at 10, thereby making an absolutely tight joint.

The bottom 1 of the roof flange is provided with an opening 11 throughwhich the soil pipe or other pipe 12 may be introduced. The opening 11is herein shown as having a transverse diameter substantially equal tothe distance between the sides 13 of the curb 3, and it has alongitudinal diy aineter which is considerably less than the distancebetween the end portions 5 and 6 of the curb so that there are portions14 and 15 of the bottom 1 which are situated with# in the outline of thecurb 3. These portions 14 and 15 constitute supports for the oakuln orother packing 4 which is placed within the curb 3.around the pipe 12.They are also of a franoible nature so that they may be readily brokenor chipped thereby to enlarge the longitudinal dimension of the aperture11. This frangible character of the bottom sections 14 and 15 may besecured in various ways. One way is to make these portions relativelythin, as shown in the drawings, so thaty they may be readily brolken orchipped by a hammer or other too The roof flange is made in the firstplace with the aperture 11 of sufficient size to easily receive the soilpipe 12 when the soil pipe extends through the bottom in a directionperpendicular thereto, as shown in Fig. 1, in which figure the device isillustrated as applied to a flat roof. When used in this way the roofflange is placed on the roof as usual and the soil pipe or other pipe isinserted through the aperture 11. The space between the pipe and thewall 3 is then packed with oakum or other suitable packing 4, and ifdesired hot lead 1'6 may be poured on top of the oakum to make a tightjoint.

' If the roof flange is to be used on a roof having a relatively steeppitch, as shown in 4ig. 3, it will be necessary to have the aperture 11enlarged somewhat in its longitudinal dimension to accommodate the pipe12. This may be readily done by breaking away the edge of one or both ofthe bottom sections 14 and 15. The shown as havin@ the greatest extentand the aperture 11 will preferably be enlarged by breaking away theedge 17 of the bottom section 15 in order to provide an aperture ofsufficient size to receive the pipe 12. When the roof ange is used on asteep pitched roof, as shown in Fig. 3, it will be necessary to breakaway the edge 17 of the bottom portion 15 until the aperture is enlargedabout to the dotted line 18, Fig. 4. After the roof flange has beenplaced on the roof, as shown in Fig. 3, the space between the pipe andcurb 3 is packed with oakum bottom section 15 is or other' packing inusual manne* and the packing ma@v be sealed by the application ot meltedlead to the top of the packing' it desired.

he device is equalliY applicable to a root having a less pitch7 as shownin Fig. 2, it onlyY being necessar)T to break away a less portion ot oneor both bottom sections lei, l5 to accommodate the pipe. ln everyinstance, the bottom sections lil) 15 constitute supports Yfor thepacking` and because the packing rests directly on the bottom it is notnecessary to make the curb 3 of very great vertical dimension. rlfhedevice is, therefore, a compact one which requires a relatively smallamount oi metal in its inanu't'acture, a tact which reduces its cost.

claim:

A root flange haring a bottom provided throughout its extent with alatface to rest Copies o this patent may be obtained for on the root andalso having a relativel)Y low oral-shaped Wall or eurb rising from thebottom a slight distance from its peripheral edge whereb;Y said edge ofthe bottom terms` a tlashinga'eeeiring iange on the exterior ot' theWall, the end portions of said Wall or curb being inclined relative tothe bottom., and said bottom extending irmardl;7 from the Wall or eurband having a pipereceiving aperture therein, the portion of the bottomsituated Within the outline of the Wall or curb constituting a supportfor the packing and being trangible so that it can be readily broken toenlarge the longitudinal dimension oit said aperture whereby the devicemay be used on either a fiat root or a pitched roof.

ln testimony whereof, l have signed my naine to this specification.
